I am working on a mod to clean the noise and dirt from the map without altering the colors. The aim is to have the map color an average of the light and dark colors created by the noise and dirt.
UPDATE Due to a random senior moment, I forgot to ask if anyone using a custom palette would be willing to share it with me so I can see if this will work with them.
Here is the preliminary work for RFB. No files from RFB are modified by this mod.
